well i shut the car off this evening and had the ac running for about 20 minutes. after i shut it off the blower stayed running with the key out of the ignition. i had it switched to the face setting and after the car is turned off it switched to floor and face. recently replaced the alternator, but that was several days ago and no problems. any ideas??

 

a little more information. i drove her again to see if i could jar it loose (the relay) and no luck but i did notice that i was not able to control the speed of the fan (1-10) it was constant at the same speed

 

posted on the other post you wrote, if u have auto temp control, blower module is probably bad.
